Master Bond Polymer Adhesive EP21TPLV-2A is a two component black colored polysulfide adhesive/sealant for high performance bonding and sealing formulated to feature medium pot life at room temperature and cure at room temperature or more rapidly at elevated temperatures. It readily develops a high bonding and sealing strength at room temperature Master Bond Polymer Adhesive EP21TPLV-2A can be applied readily after simple mixing of the two components on many different surfaces. It produces durable high strength and tough bonds and seals which are remarkably resistant to thermal cycling and chemicals including water, oil and most organic solvents, over the exceptionally wide temperature range of -60°F to more than 250°F. Adhesion to metals, glass, ceramics, wood. vulcanized rubbers and many plastics is excellent. The hardened adhesive/sealant is an electrical insulator. Master Bond EP21TPLV-2A adhesive/sealant is widely used in the electronic, electrical, computer, construction, metalworking, appliance, automotive and chemical industries. This adhesive/sealant fully meets MIL-S-8802D Class B Type II.
